Wayland Patch 9/23/12: Fireworks, Ball Gowns, Parades; Wayland Prepares for 375th Anniversary. A celebration this big requires more than just a few weeks of planning. After all, Wayland only turns 375 years old once, right? The 375th Anniversary Commemoration Committee has been hard at work for well over a year planning dozens of events, activities, educational opportunities and more to commemorate the town’s 375th anniversary. And with just under nine months until the opening celebration of the year-long party, committee chair Mary Antes said much has been accomplished, but much remains to be done.
